PROBLEM TO BE SOLVED: To find a new pharmacologically active ingredient contained in royal jelly. SOLUTION: Adenosine, adenosine N1-oxide, adenosine-5′-monophosphate (5 ′) contained in an aqueous extract of royal jelly fractionated to a molecular weight of 2000 or less. AMP), adenosine-5'-monophosphate-N1-oxide (AMP N1-oxide), nicotinamide adenine dinucleotide (NAD + ), nicotinamide adenine dinucleotide-N1-oxide (NAD + N1-oxide) At least one of these is used as an active ingredient of a human osteoblast growth inhibitor.
